Sampler Leak Test
The Sampler Leak Test determines the specific leak rates of injection valve, metering device, needle/seat, and system. The test requires that a blank nut gets installed at port 6 (outlet) of the injection valve. The test allows for setting the pressure at which it should be performed (maximum pressure allowed: 1000 bar), and it is recommended to use a pressure that corresponds to the normal operation of the system.
The test proceeds as follows:
A pump head leak test is carried out on the selected channel.
A Pressure Test is carried out in the bypass position.
A Pressure Test is carried out in the main pass position.
A Pressure Test is carried out in the main pass position with the needle at the blocked seat position.
The values obtained are then used to calculate the injection valve, metering device, and needle/seat leak rates.
At the end of the test, the results are evaluated automatically.
